Green Columns (+) and Red Columns (-) in MVC

[Ian]

When a value is greater and equal to 0, I need the column to appear Green. Red when it's less than 0.

In the attached screenshot you'll see that the grid is always the default theme color or orange.

Html.Kendo().Chart(Model.Results)
    .Name("chartPCT")
    .Title("% Return")
    .Legend(legend => legend.Visible(false))
    .Series(series =>
            series.Column(model => model.Metrics.Return)
                  .Name(Model.ColumnTitle)
                  .Labels(false)
    )
    .ValueAxis(axis => axis.Numeric()
                           .Labels(labels => labels.Format("{0}%")))
    .CategoryAxis(axis => axis
                              .Categories(model => model.Observation)
                              .Labels(labels =>
                                  {
                                      labels.Format("MMM");
                                  }))
    .Render();
